Moderate to fresh(20-30km/h) easterly to east north easterly trades would cross the islands within the next 24 hours, becoming strong(near 40km/h) late Friday into Saturday. Seas are currently slight to moderate in open waters with swells peaking at 1.0m on western coasts and 2.0m on the eastern coasts. As wind speeds increase late Friday night, sea conditions could further deteriorate. Therefore, small craft operators and sea bathers should exercise caution for above normal sea swells and occasional gusty winds.
